Re: [Xen-users] How to make a P2V domU be recognized by Xend

[Kyle Lexmond <kyl191@xxxxxxxxxx>]

Hi Tony,
Those errors look like something's wrong with libvirt -
http://wiki.libvirt.org/page/FAQ#error:_Unknown_Failure mentions that
the "Unknown failure" messages are a result of bad error reporting in
libvirt, but says more details should be available in dmesg and
/var/log/messages.log

Those libvirt versions are quite old though - I'm guessing Debian 6 is
the stable release? http://packages.debian.org/stable/libvirt-bin says
the version is still 0.8.3-5+squeeze2, when the latest release is
0.9.7 (http://libvirt.org/sources/)

Any chance of using a backport?
http://packages.debian.org/squeeze-backports/libvirt-bin is 0.9.6, so
that might work better. I'm just wondering about the Xen API line -
4.0 to 4.1 made a number of changes, so I don't know what 3.0.1 to
4.1.0 would be like, and I'm thinking that might be the source of the
errors.

That said - your config file is a standard Xen config file, so it's
strange that it'd be in /var/lib/xend/domains. You can get around
virsh to at least see if it starts - Put the config (or a copy) in
/etc/xen, and try xm create -c /etc/xen/filename. That should at least
get Xen starting the domU, but not managing it yet.
